The terminology caused endless confusion on my ATPL course.
The word "Supercharger" is a generic term for a device which boosts the manifold pressure.
There are two types of supercharger. There's an engine-driven supercharger, also known (and here's where the confusion comes in) as a "Supercharger". And there's an exhaust-driven type, known as a "Turbocharger". Some careful reading of questions was required whenever you saw the word "supercharger".
In practice, though, I agree with SSD - if you hear the word "supercharger" outside of a CAA exam it almost certainly refers to an engine-driven boost pump.
